FIRE EFFECTS
SPECIES: Tetradymia nuttallii | Nuttall Horsebrush 



IMMEDIATE FIRE EFFECT ON PLANT : 
The effect of fire on shrubs is more damaging than that on forbs and
grasses.  Fire not only destroys herbage, but destroys the stored
reserves of shrubs [3].  Nuttall horsebrush is considered a
fire-resistant species, as there is a 65 percent or greater chance that
at least 50 percent of a population will survive or reestablish after a
fire [10,11].


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Nuttall horsebrush, which is capable of resprouting and rapid regrowth
after a fire, is favored over other plants that reestablish only by seed
[2].  Postfire regeneration response is considered rapid with 2 to 5
years required to approximate preburn frequency or cover [10].  Plants
quickly regain and surpass their original size.  The amount of sprouting
is affected by season and soil moisture, as these are factors which
contribute to burning intensity [3].

After a fire, crown-sprouting Nuttall horsebrush may initially dominate
sagebrush ranges.  In addition to the vigorous postburn production of
root crown sprouts, there is dynamic seedling establishment [12].


DISCUSSION AND QUALIFICATION OF PLANT RESPONSE : 
NO-ENTRY


FIRE MANAGEMENT CONSIDERATIONS :
